Valcom SX30-T 30-Watt Paging Horn
Overview
The Valcom SX30-T is a 30-watt paging horn designed for voice paging, emergency alert systems, and loud ringing applications. Part of Valcom's SX-Series line, the SX30-T delivers high-efficiency audio output suitable for industrial facilities, warehouses, parking lots, stadiums, and mixed indoor/outdoor deployment environments. The unit supports microphone input, enabling direct voice announcements and alert distribution without requiring external audio routing.
Key Features
- 30-Watt Power Output: High-efficiency horn generates sufficient SPL for wide-coverage area paging and emergency notification across large indoor and outdoor spaces
- 25/70/100 Volt Transformer: Switchable transformer configuration accommodates standard commercial audio voltage levels, enabling integration into existing distributed audio networks without additional impedance matching equipment
- Multiple Mount Options: Supports both wall and ceiling installation, providing flexibility for facility layout and acoustic optimization
- Microphone Input Support: Accepts direct microphone connection for real-time voice paging and emergency announcements
- High-Efficiency Design: SX-Series construction prioritizes acoustic efficiency and voice clarity, ensuring intelligible speech delivery across coverage zones
- Indoor/Outdoor Rated: Suitable for both interior installations (offices, warehouses, industrial facilities) and exterior deployments (parking lots, grounds, open-air spaces)
Integration & Compatibility
The SX30-T integrates into Valcom paging systems and standard 25/70/100-volt commercial audio infrastructure. Transformer voltage selection (25V, 70V, or 100V) should be coordinated with the existing audio distribution amplifier or mixer output impedance to ensure proper power transfer and avoid distortion. Microphone input capability enables both analog mixing console integration and direct handheld announcements. The horn's efficiency rating supports long-distance paging without requiring multiple amplification stages.
Deployment Recommendations
For industrial facilities and warehouses, ceiling mounting typically provides optimal coverage distribution and reduces installation clutter on walls. Parking lot and stadium installations benefit from wall-mounted arrangements at elevated heights to project announcements across large open areas. Verify voltage compatibility with the system amplifier output before installation. Microphone input lines should use shielded audio cable to minimize noise and feedback, particularly in electrically noisy industrial environments.

During facility paging system planning, the Valcom SX30-T consistently delivers the acoustic coverage and operational flexibility needed for mixed-use environments. Its switchable transformer design eliminates the need for external impedance conversion, reducing bill-of-materials complexity and installation labor. The SX30-T (often searched as SX30 T) is a straightforward, proven choice for facilities transitioning from analog horns to higher-efficiency distributed audio systems.
Technical Highlights:
- Power & Voltage: 30-watt output with 25/70/100-volt transformer selection allows direct connection to most commercial audio amplifier outputs without additional equipment
- Microphone Integration: Built-in microphone input support enables both emergency override announcements and routine paging without console mixing complexity
- Mounting Flexibility: Wall and ceiling configuration options accommodate facility-specific layouts and acoustic requirements
Deployment Considerations:
- Confirm amplifier output impedance and voltage rating match the horn's transformer setting before installation to avoid power loss or distortion
- In high-ambient-noise environments (industrial facilities, parking structures), mount at elevated positions and verify intelligibility with test announcements before full system commissioning
- Use shielded microphone cable (minimum XLR or equivalent) to maintain signal clarity and prevent feedback in electrically noisy spaces
For facilities requiring reliable, cost-effective paging horns with minimal integration overhead, the SX30-T is a solid foundation. Its proven efficiency and voltage flexibility make it suitable for both new deployments and equipment replacement in existing systems.
